Summary: 

Difference Between GPS and DGPS is that a global positioning system (GPS) is a navigation system that consists of one or more earth-based receivers that accept and analyze signals sent by satellites in order to determine the receiver’s geographic location.

DGPS stands for Differential Global Positioning System, is an enhacement in GPS that is created to provide more location accuracy. from the 15-meter nominal GPS accuracy to about 10 cm for best implementations.

A global positioning system (GPS) is a navigation system that consists of one or more earth-based receivers that accept and analyze signals sent by satellites in order to determine the receiver’s geographic location. 

  • The first and most used application of GPS technology is to assist people with determining where they are located. 
  • The data obtained from a GPS, can be applied to a variety of other uses: creating a map, locating a lost person, monitoring the movement of a person or object, determining altitude.
  • Many vehicles use GPSs to provide drivers with directions or other information.

Satellites in the space provides signals to the earth’s surface at the speed of light, but through any atmospheric change there can be an error. And due to this error a delay can be caused, and for all these errors, DGPS is created and it adjusts these errors to provide accurate location.
